SPINNING-FRAME.

SPECIFICATION forming part of Iletters Patent N 0. 573,925, dated December 29, 1896.

Application filed July 1, 1896.

companying drawings, and to letters of ref erence marked thereon, which this specification.

The object of my present invention is to provide a spinning-frame with sectional carrying-rollers which support and are in fricform apart of tional contact with the condenser-spools having the roving wound thereon, to thus simplify the operation of spinning the roving, whereby the latter passes directly from the condenser-spools, between the drawing-rollers, onto the bobbins on the spindles.

The invention consists in the improved spinning-frame and in the combination and arrangementof the various parts thereof,substantially as will be hereinafter more fully described, and finally embodiedin the clauses of the claim.

In the accompanying drawings, Figure 1 is a transverse sectional view of a spinningframe provided with my those parts being shown which are necessary to fully illustrate the nature of my said invention; Fig. 2, a detail front elevation of Fig. 1; Fig. 3, a side elevation of a spinningmule provided with my improvements, the mule not being illustrated in detail.

In said drawings, a represents the frame, I) and c the connecting bars or braces, and cl the spindle-rails, on which the spindles 6, car- I ryin g the bobbin 6, are mounted in the usual or well-known manner.

In the frame CL and on each side of the center thereof are arranged the parallel shafts g and h, on which are mounted a series of drums or carrying-rollers g and h respectively, which rollers are in close proximity to each other. In front of the shaft g are also arranged (preferably three) sets of drawingrollers m n 0, operated in the usual manner improvement, only Serial No. 597,699- (No model.)

and driven at various speeds, as will be manifest.

Projecting from the brace 19 and secured thereto in any desired manner are the threadguides f, arranged so as to be above and substantially in the center line of their respective spindles.

0n the carryiugrollers g and 7&2 are placed the condenser-spools 2', having the roving wound thereon, which roving passes over the roller 9 into and between the sets of drawingrollers m, n, and o, by which it is drawn to the required size. From the drawing-rollers and traveler (Z (on ring d which latter is vertically reciprocated, together with the bar cl) onto the bobbins.

In Fig. 3 is illustrated the mode of applying my present invention to a spinning-mule. The bob bin-carrying spindles are arranged on the reciprocating carriage A, and the thread -K passes from the drawing-rollers through threadguides A onto the bobbins e, as will be manifest.

In operation the sectional spools t', after being iilled with roving, are taken directly from the condensenframe of a carding-machine and are placed on the carrying-rollers g and k asin Figs. 1 and 2, and remain during the operation of unwinding the roving, that is to say, winding it upon the bobbins, in frictional contact with their respective carrying-rollers.

I do not intend to limit myself to the precise construction shown and described, as various alterations can be made without changing the scope of my invention.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In a spinning-frame, the combination with its frame, of two parallel sectional carrying-rollers mounted in said frame, a series of condenserspools carrying the roving loosely arranged on said sectional rollers and having its roving in frictional contact therewith, means for preventing lateral motion of the condenser-spools, a series of drawingrollers also mounted in the frame, a spindlerail traversing the frame, and a series of bobthe roving-passes through the thread-guide f bin-carrying spindles mounted in said spinries of sets of drawing-rollers, revolving at various speeds, also mounted in the frame, a series of bobbin-carrying spindles mounted in said rail, and a series of thread-guides arranged above said spindles, all said parts,

substantially as and for the purposes de-- scribed.

In testimony that I claim the foregoing I have hereunto set my hand this 14th day of May, 1896.
